Point t"(-2,5) is a vertex of triangle t"o"p". the original image was rotated 90° counterclockwise around the origin and rhen translated (x, y)-> (×-1,y+7). what are the coordinates of the original image's point t before the composition of transformations?

The answer is -2,1

Step-by-step explanation:

So, what I did was retrace my steps and do the problem backwards. So, i rotated -2,1 to get -1,2. From there I translated it to get -2,5. When I got -2,5 I knew that had to be the one.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
